Industrial beds often have feeds coming in at temperatures different from the bed temperature. The incoming feed gas undergoes a density change as it gets heated up in the bed causing substantial bed expansion, This affects the bed behavior considerably. By proper placement of such feed nozzles one can use the changed bed behavior to preferentially affect the dynamics of the bed. Extended Abstract Status: File Uploaded | ||
